# Tests for the :tA variable modifier, which returns the absolute path for

# TODO: Implementation

|
# Between 2016-06-03 and 2020-11-14, it was possible to trick the :tA modifier
|
|
# into resolving completely unrelated absolute paths by defining a global
|
|
# variable with the same name as the path that is to be resolved. There were
|
|
# a few restrictions though: The "redirected" path had to start with a slash,
|
|
# and it had to exist (see ModifyWord_Realpath).
|
|
#
|
|
# This unintended behavior was caused by cached_realpath using a GNode for
|
|
# keeping the cache, just like the GNode for global variables.
